TECHNICAL FIELD

The present invention relates to an image processing apparatus for recording image data and discrimination information for discriminating image data in a recording medium, an image processing method and an image processing system; a data transmission apparatus, a data receiving apparatus and a data transmitting and receiving system; and a recording medium, and more particularly to an image processing apparatus for recording production information at the time of producing image data and editing information at the time of editing together with image data, and an image processing method; an image processing apparatus for transmitting production information at the time of producing image data to another apparatus to record the former together with image data, and an image processing method; an image processing system for receiving image data from another apparatus and production information to transmit position information at the editing point to another apparatus, a data receiving apparatus for receiving production information from another apparatus, and a data transmission apparatus for transmitting discrimination information to another apparatus; a data transmitting and receiving system constituted by the data transmission apparatus and the data receiving apparatus, and a recording medium having a program for the process of recording production information at the time of producing image data and editing information at the time of editing together with image data.

BACKGROUND ART

There has been popularized the art for recording information corresponding to an editing point as additional information together with image data when an image pick-up device records image data in a recording medium. An editor is able to retrieve an editing point as desired by referring to the additional information.

In the past, the additional information has been input as a photographer operates an input device provided on the image pick-up device before production. In this case, the image pick-up device records the input additional information and image data in the recording medium.

Further, one method for editing image information recorded in a recording medium such as a video tape is a off-line edition. The off-line edition is a method for copying, in a production site, image information recorded in an original tape to a separate recording tape (an editing tape) once, preparing editing data at the editing point on the editing tape, and preparing a master tape on the basis of the editing data. In the off-line edition, it is not feared that original image information recorded in an original tape, for being recording in an editing tape, is erased or rewritten by mistake, and a master tape as desired can be prepared.

However, in the off-line edition, editing work is carried out using an editing tape having an original tape copied, thus posing a problem that when information recorded on the original tape is coped on the editing tape, it takes time and involves trouble. So, one method for solving such a problem as noted above is a method for copying information on the original tape on a disk-like recording medium capable of recording and capable of random accessing such as a hard disk once, and preparing editing data using copied information on the disk-like recording medium. According to this method, since the time for getting access to the editing point is shortened, the time required for the editing work can be shortened. However, in the conventional editing device, when CG or the like is combined with image data, an editor need to input it, and data base is so enormous that work which is troublesome for an editor results. Further, for example, in a case where other information such as a map is combined with an image for display it, it has been necessary to retrieve and extract other information such as a map to be combined with image data from the data base.

On the other hand, with the popularization of communication making use of a network line (circuit) such as a so-called Internet in which a plurality of networks to thereby constitute an imaginary network, distribution of various content data such as image data, voice data and so on becomes enabled using the network line such as an Internet. With this, a broadcasting station for producing and broadcasting programs becomes necessary to administrate individual detailed information even with respect to fragmentary image data and voice data. More concretely, it is necessary to distribute various additional information such as information for discriminating a broadcasting material produced as a program in a broadcasting station or the like, information relating to copyright of contents, and so on together with contents.

BEST MODE FOR CARRYING OUT THE INVENTION

In the following, an image processing apparatus and an image processing method, an image processing system, a data transmission apparatus and a data receiving apparatus, a data transmitting and receiving system, and a recording medium according to the present invention will be described in detail with reference to the drawings.

The image processing system according to the present invention is, in an image processing apparatus for recording image data in a recording medium, an image processing apparatus comprising an input part for inputting image data, a recording part for recording production information in connection with photographing transmitted from other apparatuses and image data in a recording medium, a detection part for detecting a recording position on the recording at an editing point of image data recorded by the recording part, and a transmission part for transmitting information of the recording position detected by the detection part. This can be applied, for example, to an image processing system in which in a broadcasting station, an image producing company and the like, an image and voice or the like (hereinafter referred to as material) are edited and processed to produce an image for broadcasting, and the image is archived. Particularly, the image processing system according to the present invention is an image processing system in which information for identifying material is recorded in a recording medium or an exclusive-use recording server to thereby relieve a burden on a photographer or an editor, and when material is utilized, the material can be identified easily.

Hereupon, a description will be made of a case where the image processing system according to the present invention is applied to a step of producing a program in a broadcasting station and a program producing company. The stages for producing a program in a broadcasting station include an anterior photographing state 10, a photographing producing stage 20, a posterior photographing stage 30, a broadcasting stage 40, and an archive stage 50. The image processing system according to the present invention gives rise to an advantage that in the above-described stages, identification information for identifying image data and voice data is suitably added and recorded in a recording medium or an exclusive-use recording device whereby when image data and voice data are utilized, these material data can be retrieved immediately to put it to practical use for editing or the like.

It is noted that metadata can be mentioned as identification information to be added. The metadata termed herein is data for described information necessary for identifying material, for example, such as the gathering time, a gathering ID, a gathering title, and a reporter name.

For example, a case where a news program is produced in a broadcasting station will be described with reference to FIG. 1. Here, FIG. 1 explains a flow of work when a news program is produced, and is different from a so-called block diagram showing constitutional elements of apparatus or the like.

The news program production in a broadcasting station can be classified into five stages, as shown in FIG. 1, pre-production 10, production 20, post-production 30, distribution 40, and archive 50.

The pre-production 10 is a stage in which the persons concerned such as a producer, a director, an announcer, a gathering staff or the like make arrangements for broadcasting contents of a news program, in which stage, the decision of broadcasting items, the assignment of a relay mobile, a gathering machine, a gathering crew or the like are also carried out. This is shown as a planning step 11 in FIG. 1.

The production stage 20 is principally a stage for collecting an image and a voice, and in FIG. 1, acquisition step 21, ingest step 22, and voice over step 23 correspond to the production stage 20.

The acquisition step 21 shows “acquisition” for collecting an image and a voice. The ingest step 22 is a step of acquiring an image and a voice (hereinafter referred to as material) obtained by the acquisition. The ingest step 22 corresponds, for example, to archiving a video cassette tape or the like having material recorded in an archive shelf, or storing data of material in a material ingesting server. The voice over step 23 is a step of inserting a voice such as narration into an image.

The post-production step 30 is a step of editing the collected material to finish it into a state that can be broadcast. In FIG. 1, computer graphic (CG) preparing step 31 and complete edit step 32 correspond to the post-production step 30.

The computer graphic (CG) preparing step 31 is a step of preparing an image by the computer graphics, and preparing a map, a weather map, a letter or the like while being put on an image. The complete edit step 32 is a step of editing material on the basis of contents decided by the planning step 11.

The distribution stage is a step of on-air (broadcasting) material edited, and in FIG. 1, closed caption step 41, live 42, automation step 43 and distribution step 44 correspond to the distribution stage 40.

The closed caption step 41 shows a work step of preparing letters for letter distribution. The live 42 shows a case where a relay at real time is broadcast during broadcasting of a news program. The automation step 43 shows a work controlled by a computer to mix material edited, a closed caption signal and image data of the live 2 and produce a news program for broadcasting automatically. In the distribution step 44, a news program for broadcasting produced in the automation step 43 is transmitted.

The archive stage 50 is a stage for archiving image data and voice data, and in FIG. 1, near line archive step 51 and archive step 52 correspond to the archive stage 50.

The near line archive step 51 shows a step of temporarily archiving material to be likely used one of these days out of materials edited. The archive step 52 shows archiving material for a long period.

NCS 60 shown in FIG. 1 is a newsroom computer system, which is a system for generally administrating information of the whole newsroom. In the NCS 60, material administration such as administration of on-air items, and how individual material is processed in what stage, and buying and selling of material relative to a broadcasting station is also administrated. Further, in the NCS 60, a journalist sometimes prepares an article from a terminal connected to the NCS 60.

Next, in a case where a news program is produced, an example of metadata input in the aforementioned steps is illustrated. Details of the data construction of metadata will be described in detail later.

First, in the planning step 11, the decision of broadcasting items, and the assignment of a relay car, a gathering machine and a gathering crew are carried out. In the planning step 11, broadcasting contents of a news program is studied, and metadata is input on the basis of contents studied. FIG. 2 shows an example of metadata. Metadata decided in the planning step 11 include Gathering_Start_DateTime representative of photographing start time, Gathering_End_DateTime representative of photographing end time, Gathering_Location_Place representative of a photographing location name, Photographer representative of a photographer name, Journalist Information representative of information relating to a journalist, Director representative of a director for a news program, Producer representative of a producer for a news program, Title representative of a news gathering title, Contents having other information relating to photographing contents, and NCS ID as an identifier (ID) set every news program and broadcasting item registered in a newsroom computer system (NCS).

In the planning step 11, the metadata illustrated above are written in a memory or the like provided on the NCO 60. It is noted that the metadata described in the planning step 11 are modified and suitably rewritten in the step described later.

Doing the course of shifting to the acquisition step 21 from the planning step 11, metadata is transmitted to equipment for carrying out acquisition in the acquisition step 21, that is, the image pick-up device. An example of metadata transmitted is shown in FIG. 3. It can be contemplated that the course shifting from the planning step 11 to the acquisition step 21 termed herein is, for example, a period in which a relay car moves toward a gathering place.

In this course, metadata representative of Gathering_Start_DateTime, Gathering_End_DateTime, Gathering_Location_Place, Photographer, Journalist Information, Director, Producer, Title, Contents, and NCS ID are transmitted to an image pick-up device moving to a gathering place from a broadcasting station on the basis of contents of a news program studded in the planning step 11.

In the acquisition step 21, gathering is carried out. In the image pick-up device for recording material data used in the acquisition step 21, metadata received by a wireless communication are stored in a memory provided in the image pick-up device. The image pick-up device reads, when an image is photographed, the metadata from the memory to record it in the recording medium together with image data and voice data. At this time, the image pick-up device inputs, in addition to metadata transmitted from a broadcasting station, new metadata generated automatically. An example of metadata input newly is shown in FIG. 4A.

Metadata input newly in the acquisition step 21 include, in addition to the metadata shown in FIG. 3, Gathering_Location_Latitude (GPS latitude), Gathering_Location_Longitude (GPS longitude) and Gathering_Location_Altitude (GPS altitude) showing information detected by GPS (Global Positioning System), Gathering_Location_Time (GPS Time) detected by GPS, Gathering_Location_Place (location name) representative of a location name of a gathering place, machine ID which is ID every image pick-up device, Camera Setup Information showing lens information, Reel Number for identifying a recording medium, Duration (Time) showing time required for photographing, SOM (Start Of Material) showing start time of each scene, Good Shot Mark and RFC Start Mark, Audio Channel Information showing assignment of a microphone, Audio Type showing a recording method for voice, UMID (Audio) and UMID (Video) for identifying material, and Copyright representative of copyright.

The above metadata are input into a recording medium and an exclusive-use recording server. The above metadata modified in the stage of the acquisition step 21 are sometimes transmitted to SCS 60 for use.

As a transmission format for transmitting image data, voice data and metadata in the image processing system 1, there is used SDI (Serial Digital Interface) which is a digital data transmission format standardized by SMPTE (Society of Motion Picture and Television Engineer, Inc.). FIG. 12A shows the constitution of the whole SDI format data.

The SDI format has EAV (End of Video) region of 4-dit showing end synchronism, ancillary(ANS) region of 268-dot, SAV (Start of Video) region of 4-dot showing start synchronism, and an active video region of 1440-bit, which is constituted by line number 525. However, numeral in a parentheses indicates a value defined by PAL (Phase Alternation Line) system.

The active video region has a vertical blanking part (VBK₁) of 9 lines, an optional blanking part (OBK₁) of 10 lines, an active video part (OCV₁), a vertical blanking part (VBK₂) of 9 lines, an optional blanking part (OBK₂) of 10 lines, and an active video region (ACV₂).

SDI is a so-called DI format, which is a format for transmitting non-compression digital data such as D2 format, in which voice data is stored in the ancillary region, and video data such as D1 and D2 are stored in the active video region for transmission. In the SDI format, metadata is inserted into the ancillary region and transmitted.

FIG. 12B shows 1 line of the SDI format. When transmitted, data of 1 line 10-bit width is subjected to parallel-serial conversion and transmission path coding and transmitted.

Further, as a transmission format for transmitting image data, voice data, and metadata in the image processing system 1, there may be used, in addition to the aforementioned SDI format, SDTI (Serial Digital Transfer Interface) format for transmitting compression data compressed by MPEG system or DV system, and SDTI-CP (Serial Digital Transfer Interface—Content Package) format in which the SDTI format is further limited.

FIG. 13A shows the data construction of the SDTI format. The SDTI format has, similar to the SDI format, EAV (End of Video) region of 4-dit showing end synchronism, ancillary(ANS) region of 268-dot, and SAV (Start of Video) region of 4-dot showing start synchronism, but the active video region constituted by line number 525 in the SDI format is defined as a payload region. However, a numeral in a parentheses shows a value defined by PAL (Phase Alternation Line).

The payload region in the SDTI format has a blank data part (BDT₁, BDT₂) and data part (DT₁, DT₂) but the line number of each data part is not defined.

FIG. 13B shows 1 line of the SDTI format. When transmitted by the SDTI format, data of 1 line 10-bit width is subjected to parallel-serial conversion and transmission path coding and transmitted.

In the SDTI format, SDTI header data of 53 words into which a transmission source address, an address, and a line number CRC are inserted are contained in the ancillary region. In the SDTI format, metadata is inserted into a region of a portion except SDTI header data of the ancillary region.

FIG. 14 shows the data construction of a SDTI-CP format. The packet construction in SDTI-CP is composed by further limiting the SDTI format, in which the constitution of the payload is modified so that various data may be inserted easily.

Data transmitted by the SDTI-CP format includes MPEG (Moving picture Expert Group) 2 Video Elementary Stream and the like, and various data such as auxiliary data including voice and metadata can be transmitted collectively.

Data inserted into the payload are divided by “items”, and various data are inserted into the items. Concretely, there are four items, System Item, Picture Item, Audio Item, and Auxiliary Item.

The System Item has regions such as System Item Bitmap, Content Package rate, SMPTE Universal Label, Package Metadata Set, Picture Metadata Set, Audio Metadata Set, Auxiliary Metadata Set, etc.

In the SDTI-CP format, metadata are regions of Package Metadata Set, Picture Metadata Set, Audio Metadata Set, and Auxiliary Metadata Set of System Item and transmitted.

Metadata are proper data added to identify material such as image data and voice data, and are transmitted on the basis of data format of KLV (Key Length Value) protocol and UMID (Unique Material Identifier) based on the SMPTE Standard.

The KLV format is a data transmission format provided with three regions, Universal Label Data Key of 16 bytes describing Universal Label Data, Value Length showing data length of metadata stored in a Value region, and Value in which actual metadata corresponding to SMPTE Dictionary. FIG. 15 shows the KEV format.

The Universal Label Data Key is a data region for applying proper labelling to metadata stored. The Universal Label Data Key is further divided into a UL (Universal Label) Header region including Object ID of 1 byte and UL (Universal Label) Size, a UL (Universal Label) Designators region including SMITE Design, Registry Design, Data Design and Reference Version, and a Data Element Tag region of 9 bytes.

UMID is an identifier decided solely in order to identify image data, audio (voice) data and other material data. FIG. 16 shows the data construction of UMID.

UMID is composed of Basic UMID as ID for identifying material data comprising a series of image, voice and metadata (hereinafter referred to as contents), and Extended UMID as a signature for identifying contents in material data.

Basic UMID has a data region of 32 bytes, and is composed of a Universal Label region of 12 bytes, a Length Value region of 1 byte, an Instant Number region of 3 bytes, and a Material Number region shown by 16 bytes.

The Universal Label region stores therein a symbol for identifying digital data, details of which are standardized in SMITE-298M. The Length Value region shows length of UMID. Basic UMID is different in length of symbol from Extended UMID. The Length Value region is shown, in case of Basic UMID, by 13 h, and is shown, in case of Extended UMID, by 33 h. The Instant Number region shows whether or not substitute process and editing process to material data are applied. The Material Number region has three regions and stores therein a symbol for dividing material data.

Time Snap shown by 4 bytes shows a snap clock sample number a day, and shows preparing time of material data in clock unit. Rn (Random Number) of 8 bytes is a random number for avoiding that a double number is attached, in a case where inaccurate time is set, or in a case where for example, a network address of equipment defined by IEEE (The Institute of Electrical and Electronics Engineer, Inc.) is changed.

On the other hand, Extended UMID is composed of Time/Date Code of 8 bytes for identifying time and data by which material is produced, Spatial Co-ordinates of 12 byes defining position information expressed by latitude, longitude and altitude, Alphanumeric Code (Country) of byte defining country name 4 by letters of alphabet omitted or symbols, Alphanumeric Code (Organization) of 4 bytes defining an organization name by letters of alphabet omitted or symbols, and Alphanumeric Code (User) of 4 bytes defining a user name that produced material.

The above-descried Basic UMID and Extended UMID include no metadata showing image size and generation number. Particularly, Material Number shows no status of material and other information relating to an image of material. Metadata showing image size and generation number are transmitted on the basis of the KEV format.

The image pick-up device 101 receives metadata through the base station 104 and the portable telephone 102 from the data administrative device 103 connected to the material administrative device 108. Accordingly, the transfer of data between these devices corresponds to the case where the image pick-up device 101 moving in the course of shifting to the gathering 12 from the planning step 11 in FIG. 1 transmits metadata from the broadcasting station.

The image pick-up device 101 is a digital video camera, comprising at least an image voice input part 131 for inputting image and voice, an operating part 132 for carrying out operation of the image pick-up device 101 and inputting of metadata, HDD (Hard disk Drive) 133 in which OS (Operating System) of a microcomputer 140 described later is recorded, a recording part 134 for recording at least an image and voice with respect to the recording medium 105, a multiplexer 135 for multiplexing an image and voice and other data, a memory 136 for mainly storing metadata, a bluetooth device 137 as a wireless interface relative to the portable telephone 102, a GPS receiving part 138 for receiving a GPS (Global Positioning System) signal to detect position information, an antenna 139 for receiving the GPS signal, and a microcomputer 140 for summing up and controlling the aforementioned constitution.

The image voice input part 131 has a circuit for image picking-up in CCD (Charge Coupled Device) not shown, or a circuit for recording such as a microphone, in which the image and voice input are converted into image data and voice data on the basis of instructions from the microcomputer 140 to supply them to the multiplexer 135.

The operating part 132 has various buttons and switches not shown and carries out operation with respect to the image pick-up device 101. Further, metadata is input as necessary.

In HDD 133 are recorded OS (Operating System) of the microcomputer 140, and a software for controlling the portable telephone 102, and the microcomputer 140 suitably read these data for use. Further, In HDD 133, data is written by the microcomputer 140.

The recording part 134 has a recording/reproducing head for recording and or reproducing image data, voice data and metadata in a recording medium though not shown, and records image data being controlled by the microcomputer 140 and supplied from the multiplexer 135 in the recording medium. Further, the recording part 134 detects metadata described in the recording medium on the basis of instructions from the microcomputer 140 to supply it to the microcomputer 140.

The multiplexer 135 is controlled by the microcomputer 140 and multiplexes image data supplied from the image voice input part 131 and metadata supplied from the microcomputer 140 to supply them to the recording part 134.

The memory 136 is a so-called EPROM (Erasable and Programmable ROM) which is erasable and programmable, which stores metadata supplied from the data administrative device 103 on the basis of instructions from the microcomputer 140. Further, the memory 136 supplies metadata stored to the multiplexer 135 on the basis of the instructions from the microcomputer 140.

The bluetooth device 137 is used as a wireless interface relative to the portable telephone 102, and is controlled by the microcomputer 140 to receive metadata supplied from the data administrative device through the portable telephone 102. Further, the bluetooth device 137 supplies tape position information output from the microcomputer 140 to the data administrative device through the portable telephone 102.

The bluetooth termed herein is a short distance wireless communication using a radio wave in 2.4 GHz band provided by Ericsson Ltd. (Sweden). The maximum transfer speed of the bluetooth is 1 Mbit/sec., and as the modulation system, GFSK (Gaussian Frequency Shift Keying) is used. Further, the maximum transfer distance of the bluetooth is 10 m (output: 1 mW) and 100 m (output: 100 mW), and the maximum transfer distance depends upon uses.

The GPS receiving part 138 receives a GPS signal through the antenna 139 to detect position information of the image pick-up device 101. The position information is expressed as latitude, longitude and altitude.

The microcomputer 140 houses therein, though not shown, CPU (Central Processing Unit), RAM (Random-Access Memory) and ROM (Read Only Memory) to sum up and control the above-described constitutions and to control operation of the whole digital video camera corresponding to a signal from the operating part 132. Various metadata relating to photographing are produced.

On the other hand, the data administrative device 103 is a computer connected, for example, to a telephone line network to enable communication with the joint administrative device 111, and is installed, for example, in a broadcasting station to which a photographer who uses the image pick-up device 101 to carry out photographing belongs. A microcomputer 141 provided on the data administrative device 103 sums up and controls the whole operation of the data administrative device 103. When the microcomputer 141 controls a communication part 142 and receives a signal from the image pick-up device 101 through the portable telephone 102, the microcomputer 141 identifies a telephone number of the portable telephone 102 to recognize the image pick-up device 101 being used by a photographer who owns the portable telephone 102 as a transmission source. The data administrative device 103 transmits metadata corresponding to the recognized image pick-up device 101 to the portable telephone 102.

In the following, operation of the respective devices when a news program is produced using the aforementioned image processing apparatus 1 will be explained. First, contents of gathering are decided in the stage of the planning step 11 shown in FIG. 11. In the joint administrative device 111 shown in FIG. 8, metadata relating to the gathering are input on the basis of the gathering contents. In the joint administrative device 111, the metadata are transmitted to the data administrative device 103 for transmitting the metadata to the image pick-up device 101 going to gathering. Metadata are transmitted to the image pick-up device 101 by the data administrative device 103.

First, operation of the image pick-up device 101 will be explained with reference to FIG. 21. When the operating part 132 is operated in a predetermined timing by a user who takes photograph using the image pick-up device 101 to indicate a transfer request of metadata, the microcomputer 140 of the image pick-up device 101 controls, in Step S1, the bluetooth device 137 to request through the portable telephone 102 that the data administrative device 103 transfer metadata to the bluetooth device 137.

The metadata transferred is metadata decided in the stage of the planning step 11 shown in FIG. 1. Concretely, this corresponds to metadata representative of a gathering location name, a photographer, a journalist, a director, a description relating to contents, gathering start date time, gathering end date time, a producer, a news gathering item, and NCS ID.

However, out of the above-described metadata, metadata other than the description relating to contents and the news gathering item are metadata input temporarily, which are suitably modified in the step described later.

This metadata is input every image pick-up device before starting gathering from the material administrative device 108 on the basis of the gathering plan before gathering, and is stored in advance in the recording part of the material administrative device 108 not shown in FIG. 8.

The individual image pick-up device is assigned in advance, and is recognized by ID stored in the memory 136, or the telephone number of the portable telephone together with the image pick-up device 101. Accordingly, metadata of a plurality of image pick-up devices are controlled every machine ID of the image pick-up device or the telephone number of the portable telephone 102.

Metadata shown in FIG. 22 is for the image pick-up device 101 used for gathering together with the portable telephone 102 whose telephone number is, for example, “090-xxxx-xxxx”.

In this case, as the gathering start date time, “2000/3/3 9:00-10:00”, “2000/3/3 13:00-14:00”, and “2000/3/3 17:00-19:00” are shown, and NCS ID corresponding thereto are shown as in “0001”, “0002”, and “0003”. Corresponding to the NCS ID, as news gathering titles, there are shown “Prime minister interview”, “Street interview”, and “Press club gathering”. Similarly, a photographer and a journalist are shown corresponding thereto.

Hereupon, the process in the data administrative device 103 when transfer of metadata is requested from the image pick-up device 101, in the step of Step S1, will be explained with reference to FIG. 23.

When a request of metadata from the image pick-up device 101 is received through the portable telephone 102, the data administrative device 103 recognizes in Step S21, the telephone number of the portable telephone 103 transmitting the received metadata or the machine ID of the image pick-up device 10.

In Step S22, the data administrative device 103 transmits, out of metadata of the image pick-up device 101 corresponding to the telephone number of the portable telephone 102 received, metadata corresponding to the time received to the portable telephone 102. For example, supposing that the image pick-up device 101 requests transfer of metadata at 9:00 on Mar. 3, 2000, the data administrative device 103 transmits metadata representative of a news gathering title “Prime Minister interview”, a photographer and a journalist corresponding to NCS ID “0001” corresponding to that time to the image pick-up device 101 through the portable telephone 102.

Now returning to FIG. 21, a description will be made. In Step S2, the bluetooth device 137 receives metadata from the data administrative device 103 through the portable telephone 102, and notifies the microcomputer 140 the reception thereof.

In Step S3, the microcomputer 140 receives a notice telling that metadata are received from the bluetooth device 137, and temporarily stores the metadata received by the bluetooth device 137 in the memory 136.

In Step S4, the microcomputer 140 judges whether or not recording is started, and if judgement is made that recording is not started, the procedure proceeds to Step S5, and in a case where the status of recording standby is released, the microcomputer 140 terminates its process. On the other hand, in a case where recording standby is not released, the procedure returns to the step of Step S4. That is, the image pick-up device 101 repeats the processes of Steps S4 and S5 till recording standby is released to assume status of recording start waiting.

In Step S4, when judgment is made that recording is started, the procedure proceeds to Step S6, the microcomputer 140 controls the recording part 134 to read a time stamp at a recording start point of the recording medium to store it in the memory 136, and controls the bluetooth device 137 to transmit it to the data administrative device 103 through the portable telephone 102.

Further, the microcomputer 140 controls the image voice input part 131 to output image data to the multiplexer 135, and controls memory 136 to output metadata stored in the memory 136 to the multiplexer 135.

In Step S7, the microcomputer 140 controls the multiplexer 135 to multiplex image and voice data and metadata to supply them to the recording part 134 in the SDI format.

In Step S8, the recording part 134 records data in the SDI format having image data, voice data and metadata supplied from the multiplexer 135 multiplexed in the recording medium.

In Step S9, the microcomputer 140 judges whether or not recording is ended, and in a case where recording is not ended, status of recording end waiting, that is, recording status is continued.

On the other hand, when judgement is made that recording is ended in Step S9, the microcomputer 140 controls, in Step S10, the recording part 134 to read a time stamp showing a recording end point of the recording medium, and controls the bluetooth device 137 to transmit tape position information of the recording start point and the recording end point read to the data administrative device 103 through the portable telephone 102 to end the process.

The recording medium shown in FIG. 8 is, for example, a tape-like magnetic recording medium, particularly showing a digital video tape. The recording medium is able to record image and voice as digitalized image data and voice data, and is provided with a region capable of recording auxiliary data such as metadata other than image data and voice data. Further, the non-volatile memory 105 a may be provided on the recording medium casing 105 so that auxiliary data is stored in the non-volatile memory 105 a.

In the following, there will be explained the process when the data administrative device 103 receives tape position information from the image pick-up device 101. When the data administrative device 103 receives tape position information from the image pick-up device 101 in Step S10 of FIG. 21, the data administrative device 103 recognizes the telephone number of the portable telephone 102 which is a transmission source of the received tape position information in Step S31 shown in FIG. 24.

In Step S32, the data administrative device 103 adds the above tape position information to metadata corresponding to the recognized telephone number out of metadata recorded in HDD not shown to record it.

While in the above explanation, a description has been made illustrating a photographer, a journalist, gathering state date time, a news gathering item, and NCS ID out of a gathering location name, a photographer, a journalist, a director, description relating to contents, gathering state date time, gathering end date time, a producer, a news gathering item, and NCS ID, it is noted that the same is true for a director, description relating to contents, gathering end date time, and a producer.

Further, there is metadata produced by the image pick-up device 101, added automatically and input. Concretely, the metadata are metadata, out of those shown in FIGS. 9 to 11, representative of gathering position (GPS latitude), gathering position (GPS longitude), gathering position (GPS altitude), gathering position (GPS time), a gathering location name, UMID (video), UMID (audio), a photographer, a journalist, a good shot marker, camera set up information, machine ID, a take number, a material start code, description relating to contents, an audio channel division, an audio type, gathering start date time, gathering end date time, a file owner, a shot number, a recording terminal, a recording port, right, and a news gathering title.

By recording metadata representative of information relating to material and tape position information in the recording medium and the data administrative device 103 as described above, it is possible to immediately retrieve and edit material data recorded in the recording medium.

Material data and metadata collected by the image pick-up device 101 and recorded in the recording medium are reproduced by the recording/reproducing device 106 shown in FIG. 8 and supplied as data of the SDI format to the material accumulation device 108. In the material accumulation device 108, image data, voice data and metadata transmitted in the SDI format are respectively separated and recorded in the recording part 173.

The controller 176 modifies contents of metadata as necessary, and produces new metadata. Metadata produced newly are metadata representative of UMID (video), UMID (audio), UMID (data), UMID (system), a good shot marker, a take number, a gathering start time code, description relating to contents, a valid date, an audio channel division, an audio type, source information, a recording format, a compression ratio, an audio channel number, an audio compression ratio, an audio sampling frequency, audio data size, a recording method, material ID, a sub-key, length of a file, gathering start date time, gathering end date time, a recording operator, a file owner, a shot number, a gathering period, GOP size, resolution, essence size, an object type, index, kind of index, an index memo, a sene number, a reel number, right, NCS ID, and a file status shown in FIGS. 9 to 11.

As described above, the material accumulation device 108 adds, when material is temporarily accumulated, metadata as described above to the recording part 173 of the material accumulation device 108 and the recording medium to input them whereby material can be identified clearly, and material data can be immediately retrieved and edited.

Image data, voice data and metadata recorded temporarily in the material accumulation device 108 are sent to the editing device 109 at timing according to necessity.

On the other hand, in the press terminal 112 connected to the joint administrative device 111, rough editing and article preparation are carried out by a journalist. When rough editing is carried out and an article prepared through the press terminal 112 is input, an editing decision list, and metadata representative of script shown in FIGS. 9 to 11 are added and input.

Further, the editing device 109 uses, out of the above-described metadata, metadata representative of, for example, gathering position (GPS latitude), gathering position (GPS longitude), gathering position (GPS altitude), gathering position (GPS time), a news gathering title, and script to prepare a CG combined image plane automatically. In the press terminal 112, a journalist may carry out rough editing on the basis of the CG combined image plane prepared automatically to edit the CG combined image plane freely.

The automatically combined CG combined image plane is further edited by an operator operating a GUI (Graphical User Interface) image plane. Operation of editing in the GUI image plane will be explained with reference to FIGS. 25, 26 and 27.

FIG. 25 schematically shows a GUI image plane 200 for editing a CG combined image plane prepared automatically. In FIG. 25, an image 201 shows a frame for staring CG combination. An image 202 shows a frame for ending CG combination. A combined image 203 shows a CG combined image plane prepared automatically. A manual selection button 204 is a button for carrying out selection for switching to an image plane on which position change for combining CG is carried out manually. A template selection button 205 is a button for changing combined position of CG. Templates 206, 207, 208, 209, 210 and 211 show the respective patterns of combined position of CG. In FIG. 25, it is displayed by a position pattern of the template 208 to which a frame is attached. A scroll bar 212 is a scroll bar for selecting templates 206 to 211.

Editing of CG combined image plane is carried out on the basis of steps shown in FIG. 26 and FIG. 27. The steps shown in FIG. 26 and FIG. 27 show a process in which the template selection button 205 is selected, and the CG combined image plane is displayed on the basis of the prepared template.

A process for synthesizing and displaying a map relating to image data will be explained with reference to FIG. 26. In Step S40, image data and metadata representative of position information are input. Then, in Step S41, a map corresponding to position information is read out of a recording server recording a map or the like not shown on the basis of position information shown by metadata. In Step S42, a CG combined image plane is prepared automatically.

Then, in Step S43, when a change of a template is instructed, the CG combined image plane based on the template is displayed in accordance with the instructions in Step S44.

On the other hand, a process for synthesizing and displaying time information relating to image data or a title is shown with reference to FIG. 27. For time information, title or the like, metadata representative of time information and metadata representative of a title are used. That is, in Step S50, image data and metadata as time information and title information are input. Then, in Step S51, a CG combined image plane is prepared automatically.

Then, when in Step S52, a change of a template is instructed, the CG combined image plane is changed in accordance with the instructions and displayed in Step S53.

For example, information of time information, the form of a character of a title, character size and the like are sometimes read from a recording server and displayed.

As described above, by using metadata showing position information decided by GPS and metadata showing contents of an article, it is possible to extract map information and characters displayed on the image plane and to carry out the CG combined image plane automatically using the extracted characters.

Following the rough editing, the complete editing is carried out in the editing device 10. In the complete editing, further strict editing is carried out in order to place material roughly edited in an actually broadcasting state. With the editing, concretely, metadata representative of a director, a producer, and an editing decision list out of metadata shown in FIGS. 9 to 11 are newly input. With respect to metadata other than those described above, metadata used in the previous stages or metadata input in the previous stage are used again. In the complete editing, various information described as metadata are used for editing.

Metadata representative of EDL Information, Script input in the press terminal 112 is decided in the complete editing process in the editing device 109.

Broadcasting material edited in the editing device 109 is mixed with other information added in the authoring terminal 115 and the media caster 116 in the multiplexer 117 and sent to the delivery pat 119 in FIG. 8.

The process for delivering broadcasting material from the delivery part 119 corresponds to the broadcasting step 44 in FIG. 1. In the delivery part 119, metadata representative of change date time and a distribution flag are newly input. With respect to the above-described metadata, metadata used in the previous stage or metadata input in the previous stage is used again in the broadcasting step 44.

When delivered from the delivery part 119, metadata needed on the receiving side out of metadata shown in FIGS. 9 to 11 are extracted and transmitted.

Broadcasting material is recorded, after delivery, in the recording device for archive 114, and administrated by the joint administrative device 111. Metadata input newly when broadcasting material is recorded in the recording device for archive 114 include archive date time, an archive operator, an archive terminal, an archive flag, and a compile flag.

With respect to metadata other than those described above, metadata used in the previous stage or metadata input in the previous stage are used again in the archive stage.

According to the image processing system 1 described above in detail, when a news program is produced in a broadcasting station, in the respective stages of the prior-photograph stage 10, the photograph producing stage 20, the post-photograph stage 30, the broadcast stage 40, and the archive stage 50, metadata for identifying image data and voice data is recorded in the recording medium or the recording device, and therefore, a burden on a photographer and an editor can be relieved. Further, when an editor handles material, the material data can be immediately retrieved and edited.

While in the above explanation, a description has been made of an example in which the bluetooth device 137 is used for communication between the image pick-up device 101 and the portable telephone 102, it is noted that communication between the image pick-up device 101 and the portable telephone 102 may be carried out by arranging a serial port and a modem by wire.
